The claim is inaccurate if she's late 6 time and she shouldn't expect one lateness if the predictions are correct <span />
Answer:
The answer to your question is:
x = 4
y = -1
z = -3
Step-by-step explanation:
3 x + 2 y + z = 7
5 x + 5 y + 4 z = 3
3 x + 2 y + 3 z = 1
= 45 + 10 + 24 - (30 + 24 + 15)
= 79 - 69
Δ = 10
= 105 + 6 + 8 - (18 + 56 + 5)
= 119 - 79
Δx = 40
= 27 + 5 + 84 - ( 105 + 12 + 9)
= 116 - 126
Δy = -10
= 15 + 70 + 18 - (10 + 18 + 105)
= 103 - 133
= -30
Δz = -30
x = Δx /Δ = 40/10 = 4
y = Δy/Δ = -10/10 = -1
z = Δz/Δ = -30/10 = -3
1. The independent variable is the height that the plant grows
2.The dependent variable is the days. The range is Monday-sat aka 7.
3. As the week goes by the plant grows approximately 5mm.
1. C. Concave pentagon
2. A. 1620°
b/c (11 - 2) × 180 = 1620
3. B. 165°
b/c (24 - 2) × 180 ÷ 24 = 165
4. A. 160°
b/c (18 - 2) × 180 ÷ 18 = 160
A cube has equal sides if they are 2÷ 1/2 each then L×W×H would be (2÷ 1/2)^3. To divide fractions we multiply the reciprocal.
2÷ 1/2 = 2/1 × 2/1 = 4
4×4 = 16×4= 64
answer is V = 64 inches cubed.
